Vikings’ Adrian Peterson practicing

DAVIE, FLA. — Dolphins receiver Chad Johnson was released from a Florida jail on $2,500 bail. He had been charged with domestic violence after his wife accused him of head-butting her during an argument.

Jail officials said Johnson, 34, was released Sunday. A no-contact order has been issued that prevents Johnson from contacting his wife, Evelyn Lozada.

Around the league

PACKERS: In need of backfield depth, Green Bay signed running back Cedric Benson. The eight-year veteran left Cincinnati after four seasons with the Bengals, leading them in rushing each year. But Cincinnati showed little interest in re-signing Benson. The Packers have been plagued by injuries in what has been an unimpressive running game. Green Bay finished 27th in rushing in 2011 despite going 15-1.

JAGUARS: Jacksonville released wide receiver Lee Evans. The eight-year veteran signed as a free agent with the Jaguars in April after he was released a month earlier by Baltimore. Evans has 381 receptions for 6,008 yards and 43 touchdowns in his career.

COWBOYS: Dallas will play its preseason opener without at least six expected starters. Rookie cornerback Morris Claiborne, their first-round draft pick, will not play Monday night at Oakland. He was back at practice Saturday but had missed a week because of a sprained left knee. Also out: two-time Pro Bowl receiver Miles Austin (hamstring), Pro Bowl nose tackle Jay Ratliff (foot), defensive end Jason Hatcher (groin), linebacker Anthony Spencer (hamstring) and center Phil Costa (back).
